Headphones & earbuds

Wireless headphones' battery drains much faster than it used to

This is usually normal battery aging after a year or more of daily charge cycles, though a stuck-on feature or firmware bug can also cause it. Checking for features left on unintentionally is the quickest first step.

Symptoms

  • Battery life is noticeably shorter than when new
  • Headphones show full charge but die within an hour or two
  • Battery drains even when not in use or in the case
  • Case battery also seems to drain unusually fast

Likely causes

  • CommonNatural battery capacity degradation from age and charge cyclesRechargeable batteries lose capacity over time, and after 1–2+ years of daily use, shorter battery life is expected.
  • CommonNoise cancelling or transparency mode left on, which uses more powerThese features draw significantly more battery than standard playback.
  • PossibleHeadphones not properly turning off or entering standbyA stuck power state can keep the headphones actively draining battery even when 'off' or in the case.
  • PossibleFirmware bug affecting power managementSome firmware versions have had known bugs causing excess battery drain, later fixed in updates.
  • Less commonCase not properly charging the earbuds or itself degradedIf the case's own battery is failing, it may not be delivering a full charge to the earbuds.

What to do

  1. Turn off noise cancelling or transparency mode when not specifically needed, since these use extra power.
  2. Confirm the headphones or earbuds are fully powering off (not just going idle) when not in use, per the manufacturer's indicator lights.
  3. Check for a firmware update in the companion app, since battery-related bugs are commonly addressed in updates.
  4. Fully drain the battery to empty, then fully charge without interruption, which can sometimes recalibrate battery reporting.
  5. Check the case's own battery level (if it has a separate charge) to make sure it's not the case failing to deliver charge.
  6. Compare current battery life to the manufacturer's original rated battery life to gauge how much decline is normal for the age of the device.
  7. If the headphones are 2+ years old with heavy daily use, treat this as expected battery aging rather than a defect.

When to call a pro

If battery life has dropped drastically within the first year of use, contact the manufacturer's support, since this may be covered under warranty as a defect rather than normal wear.
